Is it the final key form factor for most of eVTOL?

It is compatible with vertical take-off, vertical landing and fast cruise speed.

It stores the energy far from the cabin and it keeps the propellers above the embarking passengers.

The streamlined twin boom design, may be the answer, holding the lifting propellers and pushing propellers behind the fuselage.

This design is more and more adopted by companies with the most promising capabilities: Volocopter and Airbus in Germany, Beta Technologies in the USA and Autoflight in China.

08th April 2017, Friedrichshafen

Friedrichshafen is home of the Zeppelin, on the side of the Constance lake. Every year, the AERO attracts its lot of light aircraft manufacturers and aviation passionates.

While many gliders, small airplanes, drones, and ultra lights were on display, we focused on the helicopters.

Harbin Aircraft Z-19 E, export version by AVIC

AVIC_Harbin_Aircraft_Z-19E_export (2)

The aircraft is displayed with a wide range of armament: KD-9 air-to-ground missiles, 57 mm rockets, TY-90 air-to-air missiles, and a 23 mm machine gun pod. 90 mm rockets are displayed on the side. However, considering the heavy rocket launcher, it may not be possible for the Z-19E to fly with both the 90 mm rockets and the anti-tank missile launcher.

Every year and a few steps away from the lake of Constance, southern Germany, the airport of Friedrichshafen hosts the AERO trade fair, gathering many manufacturers from the light general aviation.

Ultra Lights and gliders, small and light aircraft, gyrocopters and helicopters, navigation systems and digital maps, everybody had something to keep himself busy.

Of course, I headed for the helicopters. The exhibition is mostly European. Robinson was not present, as well as bigger manufacturers like AgustaWestland or Airbus Helicopters.

e-volo

e-volo is a young German company aiming for an electric “multicopter”. The Volocopter is a dream to every young engineer: the elegant concept featuring 18 electric motors (55 to 90 kW) proved its feasibility with an indoor unmanned flight last year (November 2013), and outdoor “real” flights are expected with excitement.

The aircraft will be certified as Ultra Light with a gross weight of 450 kg and 2 persons side by side.

Cruise speed would be at least 100 km/h, longer than 1 hour and higher than 6500 ft.

GUIMBAL

The two-seater is worldwide famous, but not yet big enough to seriously compete against the almighty Robinson. The Cabri is now fitted with a cargo hoist up to 220 kg and models produced after S/N 008 can be easily retrofitted.

SAGITA Helicopters

SAGITA Helicopters is a Belgian company created in 2008, working on a new helicopter design based on a Ljungström turbine. The bulky hull covers a centrifugal turbine, that powers both of the rotor plates. The 2 pairs of blades are contra-rotating coaxial rotors. According to the brochure, the transmission system requires no lubrication or cooling!
The air intake is located at the rear of the fuselage and the exhaust is a thin gap between the hemispheres of the rotor head.

Despite succesful flight tests of a 1/5 scale model and wind tunnel experiments, the full scale prototype is expected to make its maiden flight only next year.

DYNALI Helicopter Company

DYNALI is another Belgian helicopter manufacturer. The first model, the H2, was under powered and got replaced by the H2S, powered by a Subaru engine. The H3 was on display.

The H3 is available as a kit for 100 000 EUR or ready to fly for 110 000 EUR. The H2S is more performing and comes with a slightly higher price of 125 000 EUR ready for flight.

With a gross weight of 450 kg,  the H3 qualifies as a Class 6 ULM in France.

ITALIAN ROTORS Industries

Unfortunately, the staff was not available to talk about the aircraft. Nevertheless, the brochure is very detailed and plenty of information.

The two-seater is powered either with a Thunderbird 130 shp or with a Lycoming O-320 B2C (four cylinders and 160 shp) and qualifies as a French ULM with a gross weight of 450 kg.

KONNER Helicopters

Konner is an Italian helicopter manufacturer producing its own Diesel turbo engines. The TK250 produces 250 shp at 2300 rpm.

The warm welcome with big slices of prosciutto was noteworthy.

The aircraft seems to come in any colour you could imagine, inside as well as outside. It can be powered with aviation fuel (kerozene, JP-4…) as well as diesel. Example was taken from a customer in Micronesia using the helicopter as help for fishing. The aircraft is provided with the same fuel as the ship: diesel.

HELIPARK GmbH

This German company started the development of the HPC450, a small helicopter. The model has never flown yet, but the display looked promising and we could expect a maiden flight soon.

AIRBORNE Technologies

Beside the manufacturers, another company displayed its airborne sensors. The Bo105 fuselage might have been there for demonstration purpose only; I wouldn’t know where the pilot would seat otherwise 🙂

US Coast Guards published an awesome video today. The cameras are installed in the helicopter.

PORTSMOUTH, Va. — The Coast Guard rescued 14 people from life rafts in the Atlantic Ocean approximately 90 miles southeast of Hatteras N.C., Monday, and two remain missing.

The 14 people were flown to Coast Guard Air Station Elizabeth City, N.C., where they were met by awaiting emergency medical services personnel at approximately 10:15 a.m. with no life threatening injuries.
Crews aboard a C-130 Hercules and an MH-60 Jayhawk are searching for the two missing crew members. Crews aboard the Coast Guard Cutter Elm and the Coast Guard Cutter Gallatin are en route to assist with the search.
The vessel is reportedly sunk, but the mast is still visible.

Coast Guard Sector North Carolina initially received a call from the owner of the 180-foot, three mast tall ship, HMS Bounty, saying she had lost communication with the vessel’s crew late Sunday evening.
The Coast Guard 5th District command center in Portsmouth subsequently received a signal from the emergency position indicating radio beacon registered to the Bounty, confirming the distress and position.
An aircrew from Coast Guard Air Station Elizabeth City launched aboard an HC-130 Hercules aircraft, which later arrived on scene and established communications with the Bounty’s crew.
Watchstanders dispatched crews aboard two MH-60 Jayhawk helicopters crew from Coast Guard Air Station Elizabeth City.

The first Jayhawk crew arrived on scene at approximately 6:30 a.m. and hoisted five people into the aircraft, and a second helicopter arrived and rescued nine people.
The 16 people donned cold water survival suits and life jackets before launching in two 25-man lifeboats with canopies.
The vessel was reportedly taking on water and without propulsion. On scene weather was reported to be 40 mph winds and 18-foot seas.

 

The sunk ship was famous as it was a replica of the HMS Bounty. The 180 ft long (55 m) and three-masted ship was built for the 1962 film Mutiny on the Bounty and was also featured in a Pirates of the Caribbean movie (source).
